Description: This session is dealing with recent results achieved within the scope of WWRP projects such as the Research and Development Project
COPS and the Forecast Demonstration Project D-PHASE. Research topics are:
- the role of land-surface exchange on the temporal-spatial structure of convection initiation
- ABL structure in complex terrain
- aerosol-cloud-precipitation microphysics in complex terrain
- key processes leading to convection initiation
- the organisation and lifetime of convection
- predictive skill of forecast systems particularly on the convection-permitting scale
- probabilistic QPF based on variational and ensemble-based data assimilation
- key observing systems and networks in complex terrain.
